1. Quadrilaterals

2. Quadrilaterals
3.G.1. Understand that shapes in different categories (e.g., rhombuses, rectangles, and others) may share attributes (e.g., having four sides), and that the shared attributes can define a larger category (e.g., quadrilaterals). Recognize rhombuses, rectangles, and squares as examples of quadrilaterals, and draw examples of quadrilaterals that do not belong to any of these subcategories. 

3. Quadrilaterals
Quadrilateral means "four sides" (quad means four, lateral means side). A quadrilateral is a four-sided 2 dimensional polygon with four angles. There are many kinds of quadrilaterals.

4. Quadrilaterals
We are going to learn about the five most common types.

5. SQUARE

6. Square -All sides congruent -opposite sides parallel
-four right angles

7. PARALLELOGRAM

8. Parallelogram -
-Opposite sides parallel
-Opposite sides congruent

9. RHOMBUS

10. Rhombus-
-It’s a parallelogram
-four congruent sides

11. RECTANGLE

12. Rectangle - -Opposite sides parallel -opposite sides congruent
-four right angles

13. NOTE:
Squares,
Rectangles and
Rhombuses are all
Parallelograms!

14. Trapezoid

15. Trapezoid
-Only one pair of sides
is parallel.
